Effect of Solvent on The Conductance of L-Ornithine Monohydrochloride in Aqueous N,N-Dimethyl Formamide and Aqueous Dimethyl Sulphoxide
P. Manikyamba* and N. Srinivas
Abstract:
The conductances of L-ornithine monohydrochloride has been studied in water-dimethyl formamide and water-dimethyl sulphoxide mixtures of different compositions in the temperature range 300-318K. The molar conductance data collected at different concentration of the eletrolyte is analyzed using Shedlovsky and Kraus-Bray models. The limiting molar conductance is found to be dependent of the temperature and dielectric constant of the medium. The solvation computed in each solvent suggest that the solvent solute interaction are independent of the dielectric constant of the medium.
